Class AverageRangeStatisticImpl

java.lang.Object

org.glassfish.external.statistics.impl.StatisticImpl

org.glassfish.external.statistics.impl.AverageRangeStatisticImpl

All Implemented Interfaces:

InvocationHandler, AverageRangeStatistic, RangeStatistic, Statistic

public final class AverageRangeStatisticImpl
extends StatisticImpl
implements AverageRangeStatistic, InvocationHandler

An implementation of AverageRangeStatistic that provides ways to change the state externally through mutators. Convenience class that is useful for components that gather the statistical data. By merely changing the count (which is a mandatory measurement), rest of the statistical information could be deduced.
